Financial Security Compression - AI Data Preprocessing Solution

Banks, securities, and insurance generate massive transaction vouchers and report files daily, with PDF and image files being voluminous, causing storage costs to continuously rise

Financial regulations require transaction data to be retained long-term and be traceable. Audit logs must completely record every file operation and be tamper-proof

Sensitive information such as customer identity information and account data requires encrypted storage. Compression and encryption must work collaboratively to ensure data security without leakage

Regulations require financial transaction vouchers to be retained for 15+ years, creating enormous storage costs and management complexity challenges for long-term archiving

Compression and encryption executed simultaneously, supporting AES-256 and national cryptographic SM4 algorithms. Sensitive information is encrypted during the compression process, eliminating plaintext leakage risks

Comprehensively records operation logs for file upload, compression, encryption, and archiving across the entire chain. Logs feature tamper-proof design, meeting financial regulatory audit traceability requirements

Supports WORM (Write Once Read Many) storage mode, ensuring archived files cannot be tampered with or deleted, meeting financial data retention compliance requirements

Intelligently identifies voucher types and business tags, automatically categorizes for archiving, supports multi-dimensional retrieval by transaction date and business type, improving archiving management efficiency

Batch upload of transaction vouchers, reports, and document files, supporting PDF, image, OFD, and other formats

Automatically identifies sensitive information in files such as account numbers and ID numbers, marking fields that require encryption protection

Compression and encryption executed simultaneously using AES-256 or SM4 algorithms, ensuring data is encrypted and protected during the compression process

Records operation logs throughout the entire process, including operator, time, file fingerprint, and other information, with tamper-proof log storage

Writes to WORM compliant storage, categorizes and archives by business rules, supporting long-term retention and fast retrieval
